'03 4.6L - Battery Warning Light

[dlyoung1]

I've got the "battery warning light" issue, but I believe perhaps not quite the same symptoms I see in other posts, So, excuse the repetition if this has been addressed.
At cold startup, the warning light will take several minutes to come on, and will occasionally cycle on and off intermittently at highway speeds. Voltage gauge is always rock solid in the middle and never hesitates to turn over strong, so the battery is staying charged.
Am I getting faulty feedback to the PCM somehow, so it THINKS there is a problem that I don't actually have? I've seen mentions of a fuse that tends to blow and/or melt, but I haven't pursued that too far because the charging system seems to be functioning fine.
Any suggestions? Thanks!

I have the same issue the battery light goes on and the off, I was told that the battery and alternator are fine, unfortunately when I take it to my mechanic the light doesn’t come on

03 models seem to have the most electrical issues due to new fuse box. Sounds like a loose or corroded connection from the wire that feeds the light gauge. Start at fuse and work back. My 2000 just has the gauge, no charge light.
